LordofEntropy writes: Blu-ray.com reports that Sony and Panasonic have announced a new optical disc evaluation technology that increases capacity from 25GB to 33.4GB. The tech uses existing Blu-ray diodes and is accomplished via firmware upgrade. The article says that it is not know if and when the upgrade will be adopted into the Blu-ray spec. However, given that Sony and Panasonic are behind it "it will likely happen later this year."
